Get ready for one of the greatest scientific news of the century. It seems astronomers will soon be showing the first shot of a black hole. Event Horizon Telescope participants (including a series of telescopes from around the world) have scheduled a number of press conferences around the world on April 10 to make announcement about “a groundbreaking result”. So far, the details are unknown. We can assume, however, that these are the first results of their mission to capture for the first time the event horizon of a black hole. The black hole is a space-time area that has...
The concept of “day” is so obvious to us, people, that we often get surprised when we realize that the length of the day on other planets can be quite different than here on Earth. Perhaps even more shocking thing is, that so far we did’t know how long is a day on Saturn. Thanks to data collected from the Cassini mission, we have an answer to this long-standing mystery. Saturn spins around its axis for 10 hours, 33 minutes and 38 seconds. The findings are published in the Astrophysical Journal. Planetary scientists often use magnetic fields to determine the...
British and American scientists have proved that billions of years ago the Earth resembled the modern Titan, a satellite of Saturn with an atmosphere and vast seas, high mountains, rivers, dunes, mists. Everything is like Earth’s, but with one difference: the temperature of Saturn’s largest satellite is minus 180 degrees, and rivers and oceans contain hydrocarbons. The results of their research were published in the new issue of the Proceedings of the National Academy of Sciences. According to scientists, 2.4 billion years ago, the Earth’s atmosphere, like Titan’s, contained huge amounts of methane – a gas produced by microorganisms, the...
Imagine that you can get the energy from every star in a radius of 100 million light-years. Of thousands of galaxies, each of which has billions of stars. Try to imagine that you are capable of taking this kind of energy and using it in the greatest super weapon in the universe. The ruin you will cause is unimaginable. In fact, you do not have to imagine it, because all of this already exists in the form of gamma rays. What are these “space snipers” that shoot the Universe at random intervals. What happens if they hit us? Another interesting...
Why does time seem to move forward? It’s a riddle that’s puzzled physicists for well over a century, and they’ve come up with numerous theories to explain time’s arrow. The latest, though, suggests that while time moves forward in our universe, it may run backwards in another, mirror universe that was created on the “other side” of the Big Bang. Two leading theories propose to explain the direction of time by way of the relatively uniform conditions of the Big Bang. At the very start, what is now the universe was homogeneously hot, so much so that matter didn’t really...
Our home galaxy is not the thin, clean spiral we had envisioned. Researchers created the first 3D map of the Milky Way galaxy and figured out what makes it warped and twisted. So, we now know that the Milky Way isn’t flat. Scientists from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and Macquarie University in Sydney, Australia have published a new study in the journal Nature Astronomy revealing an unprecedented 3D map of the galaxy we live in. The scientists used the locations of 1339 ‘standard’ stars to map the outline of the Milky Way galaxy called Classical Cepheids....
On Jan. 19, 2019, just 161 days after its launch from Cape Canaveral Air Force Station in Florida, NASA’s Parker Solar Probe completed its first orbit of the Sun, reaching the point in its orbit farthest from our star, called aphelion. The spacecraft has now begun the second of 24 planned orbits, on track for its second perihelion, or closest approach to the Sun, on April 4, 2019. Parker Solar Probe entered full operational status (known as Phase E) on Jan. 1, with all systems online and operating as designed. The spacecraft has been delivering data from its instruments to...
The process responsible for the formation of the Earth does not imply the existence of key ingredients for life. New research, however, shows how our planet probably has acquired them. Scientists are saying a Mars-sized planet has hit the Earth about 4.4 billion years ago. On the one hand, it served as a “donor” to the important ingredients for life, as its core was rich in sulfur. On the other – it has led to the formation of the Moon, our natural companion. Experiments prove that much of the nitrogen and carbon of the Earth is the result of this...
